Speaking many languages is good, but in Switzerland, most people speak 2- 4 languages. So you wouldn't stick out that much, maybe if your German, French and Italian are perfect in talking and writing. That would be a big asset.

You put Bern as location. Find out about design companies in the Bern region and call them to make an appointment to find out if they could use your skills. Maybe they want you as a freelancer and you can work from wherever is home. Good luck.
